FIELD OF INVENTION

The present invention relates to silicone elastomer emulsion cosmeticcompositions that comprise an internal phase the further includes acolorant. These compositions are intended to deliver such colorantingredients to the skin of the user in such a manner as to provide asmooth and even colored appearance while actually providingdiscontinuous coverage.

BACKGROUND

A typical problem experienced in the application of cosmetics to theskin is the difficulty associated with controlling the deposition of thecolorants included therein, particularly pigments. This lack ofcontrolled deposition usually results in uneven application of thecosmetic such that either a cakey appearance or an uneven, blotchy lookis achieved. It is generally believed that such undesirable effects comefrom the random dispersion of the colorant materials in the composition.Oftentimes, these materials agglomerate within the cosmetic and causeclumping while packaged as well as upon application to the skin.

Applicants, however, have found a solution to the above-mentionedagglomeration problem that accompanies the use of numerous cosmetics.Applicants have found that the inclusion of colorant materials in theinternal phase of a silicone elastomer-containng emulsion-type cosmeticallows for not only smooth application but a discontinuous although evenappearing product coverage Additional advantages of these compositionsinclude a soft, smooth feel and good application.

Non-Emulsifying Crosslinked Siloxane Elastomer

The compositions of the present invention comprise a non-emulsifyingcrosslinked organopolysiloxane elastomer in the oil phase, whether suchphase is the dispersed phase or the continuous phase. The term“non-emulsifying,” as used herein, defines crosslinkedorganopolysiloxane elastomer from which polyoxyalkylene units areabsent. No specific restriction exists as to the type of curableorganopolysiloxane composition, which can serve as the starting materialfor the crosslinked organopolysiloxane elastomer. Examples in thisrespect are addition reaction-curing organopolysiloxane compositionswhich cure under platinum metal catalysis by the addition reactionbetween SiH-containing diorganopolysiloxane and organopolysiloxanehaving silicon-bonded vinyl groups; condensation-curingorganopolysiloxane compositions which cure in the presence of anorganotin compound by a dehydrogenation reaction betweenhydroxyl-terminated diorganopolysiloxane and SiH-containingdiorganopolysiloxane; condensation-curing organopolysiloxanecompositions which cure in the presence of an organotin compound or atitanate ester, by a condensation reaction between anhydroxyl-terminated diorganopolysiloxane and a hydrolyzable organosilane(this condensation reaction is exemplified by dehydration,alcohol-liberating, oxime-liberating, amine-liberating,amide-liberating, carboxyl-liberating, and ketone-liberating reactions);peroxide-curing organopolysiloxane compositions which thermally cure inthe presence of an organoperoxide catalyst; and organopolysiloxanecompositions which are cured by high-energy radiation, such as bygamma-rays, ultraviolet radiation, or electron beams.

Addition reaction-curing organopolysiloxane compositions are preferredfor their rapid curing rates and excellent uniformity of curing. Aparticularly preferred addition reaction-curing organopolysiloxanecomposition is prepared from:

(A) an organopolysiloxane having at least 2 lower alkenyl groups in eachmolecule;

(B) an organopolysiloxane having at least 2 silicon-bonded hydrogenatoms in each molecule; and

(C) a platinum-type catalyst.

With regard to the above, component (A) is the basic component of thesilicone elastomer-generating organopolysiloxane, and curing proceeds bythe addition reaction of this component with component (B) undercatalysis by component (C). This component (A) must contain at least 2silicon-bonded lower alkenyl groups in each molecule; an excellent curedproduct will not be obtained at fewer than two lower alkenyl groupsbecause a network structure will not be formed. Said lower alkenylgroups are exemplified by vinyl, allyl, and propenyl. While the loweralkenyl groups can be present at any position in the molecule, theirpresence at the molecular terminals is preferred. The molecularstructure of this component may be straight chain, branched straightchain, cyclic, or network, but a straight chain, possibly slightlybranched, is preferred. The molecular weight of the component is notspecifically restricted, and thus the viscosity may range from lowviscosity liquids to very high viscosity gums. In order for the curedproduct to be obtained in the form of the rubbery elastomer, it ispreferred that the viscosity at 25° C. be at least 100 centistokes.These organopolysiloxanes are exemplified by methylvinylsiloxanes,methylvinylsiloxane-dimethylsiloxane copolymers,dimethylvinylsiloxy-terminated dimethylpolysiloxanes,dimethylvinylsiloxy-terminated dimethylsiloxane-methylphenylsiloxanecopolymers, dimethylvinylsiloxy-terminateddimethylsiloxane-diphenylsiloxane-methylvinylsiloxane copolymers,trimethylsiloxy-terminated dimethylsiloxane-methylvinylsiloxanecopolymers, trimethylsiloxy-terminateddimethylsiloxane-methylphenylsiloxane-methylvinylsiloxane copolymers,dimethylvinylsiloxy-terminated methyl(3,3,3-trifluoropropyl)polysiloxanes, and dimethylvinylsiloxy-terminateddimethylsiloxane-methyl(3,3,-trifluoropropyl)siloxane copolymers.

Component (B) is an organopolysiloxane having at least 2 silicon-bondedhydrogen atoms in each molecule and is a crosslinker for component (A).Curing proceeds by the addition reaction of the silicon-bonded hydrogenatoms in this component with the lower alkenyl groups in component (A)under catalysis by component (C). This component (B) must contain atleast 2 silicon-bonded hydrogen atoms in each molecule in order tofunction as a crosslinker. Furthermore, the sum of the number of alkenylgroups in each molecule of component (A) and the number ofsilicon-bonded hydrogen atoms in each molecule of component (B) is to beat least 5. Values below 5 should be avoided because a network structureis then essentially not formed.

No specific restriction exists on the molecular structure of thiscomponent, and it may be any of straight chain, branch-containingstraight chain, cyclic, etc. The molecular weight of this component isnot specifically restricted, but it is preferred that the viscosity at25° C. be 1 to 50,000 centistokes in order to obtain good miscibilitywith component (A). It is preferred that this component be added in aquantity such that the molar ratio between the total quantity ofsilicon-bonded hydrogen atoms in the instant component and the totalquantity of all lower alkenyl groups in component (A) falls within therange of 1.5:1 to 20:1. It is difficult to obtain good curing propertieswhen this molar ratio falls below 0.5:1. When 20:1 is exceeded, there isa tendency for the hardness to increase to high levels when the curedproduct is heated. Furthermore, when an organosiloxane containingsubstantial alkenyl is supplementarily added for the purpose of; forexample, reinforcement, it is preferred that a supplemental addition ofthe instant SiH-containing component be made in a quantity offsettingthese alkenyl groups. This component is concretely exemplified bytrimethylsiloxy-terminated methylhydrogenpolysiloxanes,trimethylsiloxy-terminated dimethylsiloxane-methylhydrogensiloxanecopolymers, and dimethylsiloxane-methylhydrogen-siloxane cycliccopolymers.

Component (C) is a catalyst of the addition reaction of silicon-bondedhydrogen atoms and alkenyl groups, and is concretely exemplified bychloroplatinic acid, possibly dissolved in an alcohol or ketone and thissolution optionally aged, chloroplatinic acid-olefin complexes,chloroplatinic acid-alkenylsiloxane complexes, chloroplatinicacid-diketone complexes, platinum black, and carrier-supported platinum.

This component is added preferably at 0.1 to 1,000 weight parts, andmore preferably at 1 to 100 weight parts, as platinum-type metal properper 1,000,000 weight parts of the total quantity of components (A) plus(B). Other organic groups which may be bonded to silicon in theorganopolysiloxane forming the basis for the above-described curableorganopolysiloxane compositions are, for example, alkyl groups such asmethyl, ethyl, propyl, butyl, and octyl; substituted alkyl groups suchas 2-phenylethyl, 2-phenylpropyl, and 3,3,3-trifluoropropyl; aryl groupssuch as phenyl, tolyl, and xylyl; substituted aryl groups such asphenylethyl; and monovalent hydrocarbon groups substituted by, forexample, the epoxy group, the carboxylate ester group, the mercaptogroup, etc.

Examples of the production of the organopolysiloxane elastomer powderare as follows:

an organopolysiloxane composition as described above(additional-curable, condensation-curable, or peroxide-curable) is mixedwith water in the presence of a surfactant (nonionic, anionic, cationic,or amphoteric), and, after mixing to homogeneity in a homomixer, colloidmill, homogenizer, propeller mixer, etc., this is cured by dischargeinto hot water (temperature at least 50° C.) and is then dried; theorganopolysiloxane composition (addition-curable, condensation-curable,or peroxide-curable) is cured by spraying it directly into a heatedcurrent; the powder is obtained by curing a radiation-curableorganopolysiloxane composition by spraying it under high energyradiation; the organopolysiloxane composition (addition-curable,condensation-curable, peroxide-curable) or high energy-curableorganopolysiloxane composition is cured, the latter by high energyradiation, and the product is then pulverized using a known pulverizersuch as, for example, a ball mill, atomizer, kneader, roll mill, etc.,to thereby form the powder. Suitable organopolysiloxane elastomerpowders include vinyl dimethicone/methicone silesquioxane crosspolymerslike Shin-Etsu's KSP-100, KSP-101, KSP-102, KSP-103, KSP-104, KSP-105,hybrid silicone powders that contain a fluoroalkyl group likeShin-Etsu's KSP-200, and hybrid silicone powders that contain a phenylgroup such as Shin-Etsu's KSP-300; and Dow Corning's DC 9506.

Preferred organopolysiloxane compositions are dimethicone/vinyldimethicone crosspolymers. Such dimethicone/vinyl dimethiconecrosspolymers are supplied by a variety of suppliers including DowCorning (DC 9040 and DC 9041), General Electric (SFE 839), Shin Etsu(KSG-15, 16, 18 [dimethicone/phenyl vinyl dimethicone crosspolymer]),Grant Industries (Gransil™ line of materials), and lauryldimethicone/vinyl dimethicone crosspolymers supplied by Shin Etsu (e.g.,KSG-31, KSG-32, KSG-41, KSG-42, KSG-43, and KSG-44). Cross-linkedorganopolysiloxane elastomers useful in the present invention andprocesses for making them are further described in U.S. Pat. No.4,970,252 to Sakuta et al., issued Nov. 13, 1990; U.S. Pat. No.5,760,116 to Kilgour et al., issued Jun. 2, 1998; U.S. Pat. No.5,654,362 to Schulz, Jr. et al. issued Aug. 5, 1997; and Japanese PatentApplication JP 61-18708, assigned to Pola Kasei Kogyo KK.

The non-emulsifying cross-linked organopolysiloxane elastomers of thepresent invention are preferably further processed by subjecting them toa high shear (approximately 5,000 psi) treatment in the presence of asolvent for the siloxane elastomer via a Sonolator at less than 10passes. Sonolation achieves a resultant composition with elastomeraverage particle size ranging from at least 20 (or about 20) microns toabout 200 microns, preferably from about 30 to about 150 microns, morepreferably from 40 (or about 40) to about 95 microns and most preferablyfrom about 50 microns to about 90 microns as measured by the HoribaLA-910 (described below). As used herein, the term “particle size” ofthe elastomer represents the elastomer particle size in its swelledstate. By “swelled,” as used herein, means that the elastomer particleshave extended beyond their normal size and shape by virtue of theirabsorption of the solvent compound. Viscosity is best when rangingbetween above 20,000 (or above about 20,000) and about 6,000,000,preferably from about 25,000 to about 4,000,000, more preferably fromabout 30,000 to about 3,000,000, most preferably from about 40,000 toabout 2,000,000, optimally about 60,000 to about 1,500,000 cps at 25° C.as measured by a Brookfield LV Viscometer (size 4 bar, 60 rpm, 0.3sec.).

Without being limited by theory, it is believed that compositionsincorporating non-emulsifying elastomer/solvent gels that includenon-emulsifying cross-linked organopolysiloxane elastomers having anaverage particle size greater than 10 microns (or greater than about 10microns) and/or viscosities greater than 20,000 cps provide films thatexhibit improved smoothness, uniformity and evenness of particle (e.g.,pigments) distribution within the film (i.e., solid particles remaindistributed within and throughout the film as opposed to such particlesprotruding from the film into and/or across the film/air interface).

Preferably, the non-emulsifying cross-linked organopolysiloxaneelastomers do not undergo recycled processing. Without being limited bytheory, recycled processing produces broad particle size distributionscomprising particles larger or smaller than that necessary to achievethe skin feel benefits of the present invention. Specifically, gel ballsoften result from silicone elastomer particles larger than 200 micronswhile elastomer particles smaller than 10 microns reduce skin feel andviscosity benefits. Such particle size distributions result from afailure to ensure that all of the elastomer particle materialsexperience the same shear throughout the process. Typically, withrecycling, only a portion of the particles experience shear before thesesheared particles are returned to the process starting point andcombined with the remaining un-sheared particles. Similarly, the nextcycle begins with only a portion of this particle mixture experiencingbefore the newly sheared mixture particles are returned to the processstarting point and combined with the remaining un-sheared particlemixture. Importantly, even after considerable recycling, some of theparticles never actually experience shear while others experience a highdegree of shear. The result is a particle size range, which encompassesparticles both larger and smaller than those necessary to achieve thepresent invention.

In contrast, discrete pass processing, as alluded to above, ensures thatall the particles experience shear as well as the same amount of shearwith each run or pass. More specifically, no run or pass is completeduntil all the particles have experienced the same shear force.Consequently, the particle size distribution is narrower than thatproduced by “recycling” with respect to specific particle sizes. Thisresults in a better balance between gel ball formation and viscosity aswell as skin feel and viscosity. Additionally preferred non-emulsifyingcrosslinked organopolysiloxane elastomers are water dispersiblespherical powders produced as aqueous dispersions. These elastomers arecured silicone rubbers having particle sizes in the range of 0.1–100microns. The powder is dispersed in an aqueous medium containing asurface active agent (i.e., emulsifier) to ensure hydrophilicity. Thematerial can be prepared by in-situ crosslinkling in a mixtureconsisting of an alkenyl containing diroganopolysiloxane and anorganohyrdogenpolysiloxane jointly emulsified in an aqueous medium inthe presence of a surface active agent. The mechanism for thecrosslinking is a hydrosilation reaction between the alkenyl groups andin the alkenyl containing diorganopolysiloxane and the silicone bondedhydrogen atoms in the organohydrogenpolysiloxane in the presence of aplatinum compound acting as a catalyst for the hydrosilation reaction.These materials are available commercially from Shin Etsu and aredescribed in detail in U.S. Pat. No. 5,871,761. A similar material isavailable from Dow Corning as a non-ionic suspension ofdimethicone/vinyidimethicone crosspolymer (available as DC9509).

The non-emulsifying crosslinked organopolysiloxane elastomer is presentin the compositions of the present invention at concentrations of fromabout 0.1 to about 10%, optimally from about 1 to about 10%, mostpreferably from about 2 to about 4% by weight.

Solvent for the Non-Emulsifying Crosslinked Siloxane Elastomer

The compositions of the present invention comprise a solvent for thecrosslinked organopolysiloxane elastomer described above. The solvent,when combined with the cross-linked organopolysiloxane elastomerparticles of the present invention, serves to suspend and swell theelastomer particles to provide an elastic, gel-like network or matrix.The solvent for the cross-linked siloxane elastomer is liquid underambient conditions, and preferably has a low viscosity to provide forimproved spreading on the skin.

Concentrations of the solvent in the cosmetic compositions of thepresent invention will vary primarily with the type and amount ofsolvent and the cross-linked siloxane elastomer employed. Preferredconcentrations of the solvent are from about 10% to about 90%,preferably from about 20% to about 80%, more preferably from about 30%to about 70%, by weight of the composition.

The solvent for the cross-linked siloxane elastomer comprises one ormore liquid carriers suitable for topical application to human skin.These liquid carriers may be organic, silicone-containing orfluorine-containing, volatile or non-volatile, polar or non-polar,provided that the liquid carrier forms a solution or other homogenousliquid or liquid dispersion with the selected cross-linked siloxaneelastomer at the selected siloxane elastomer concentration at atemperature of from about 28° C. to about 250° C., preferably from about28° C. to about 100° C., preferably from about 28° C. to about 78° C.The solvent for the cross-linked siloxane elastomer preferably has asolubility parameter of from about 3 to about 13 (cal/cm³)^(0.5), morepreferably from about 5 to about 11 (cal/cm³)^(0.5), most preferablyfrom about 5 to about 9 (cal/cm³)^(0.5). Solubility parameters for theliquid carriers or other materials, and means for determining suchparameters, are well known in the chemical arts. A description ofsolubility parameters and means for determining them are described by C.D. Vaughan, “Solubility Effects in Product, Package, Penetration andPreservation” 103 Cosmetics and Toiletries 47–69, October 1988; and C.D. Vaughan, “Using Solubility Parameters in Cosmetics Formulation”, 36J. Soc. Cosmetic Chemists 319–333, September/October, 1988.

The solvent preferably includes volatile, non-polar oils; non-volatile,relatively polar oils; non-volatile, non-polar oils; and non-volatileparaffinic hydrocarbon oils, each discussed more fully hereinafter. Theterm “non-volatile” as used herein refers to materials which exhibit avapor pressure of no more than about 0.2 mm Hg at 25° C. at oneatmosphere and/or to materials that have a boiling point at oneatmosphere of at least about 300° C. The term “volatile” as used hereinrefers to all materials that are not “non-volatile” as previouslydefined herein. The phrase “relatively polar” as used herein means morepolar than another material in terms of solubility parameter; i.e., thehigher the solubility parameter the more polar the liquid. The term“non-polar” typically means that the material has a solubility parameterbelow about 6.5 (cal/cm³)^(0.5).

1. Non-Polar, Volatile Oils

The non-polar, volatile oil tends to impart highly desirable aestheticproperties to the compositions of the present invention. Consequently,the non-polar, volatile oils are preferably utilized at fairly highlevels. Non-polar, volatile oils particularly useful in the presentinvention are selected from the group consisting of silicone oils;hydrocarbons; and mixtures thereof. Such non-polar, volatile oils aredisclosed, for example, in Cosmetics, Science, and Technology, Vol. 1,27–104 edited by Balsam and Sagarin, 1972.

2. Relatively Polar, Non-Volatile Oils

The non-volatile oil is “relatively polar” versus the non-polar,volatile oil discussed above. Therefore, the non-volatile co-solvent ismore polar (i.e., has a higher solubility parameter) than at least oneof the non-polar, volatile oils. Relatively polar, non-volatile oilspotentially useful in the present invention are disclosed, for example,in Cosmetics, Science, and Technology, Vol. 1, 27–104 edited by Balsamand Sagarin, 1972; U.S. Pat. No. 4,202,879 issued to Shelton on May 13,1980; and U.S. Pat. No. 4,816,261 issued to Luebbe et al. on Mar. 28,1989.

Therelatively polar, non-volatile co-solvents useful in the presentinvention may be either saturated or unsaturated, have an aliphaticcharacter and be straight or branched chained or contain alicyclic oraromatic rings. More preferably, the relatively polar, non-volatileliquid co-solvent is selected from the group consisting of fattyalcohols having from about 12–26 carbon atoms; fatty acids having fromabout 12–26 carbon atoms; esters of monobasic carboxylic acids andalcohols having from about 14–30 carbon atoms; esters of dibasiccarboxylic acids and alcohols having from about 10–30 carbon atoms;esters of polyhydric alcohols and carboxylic acids having from about5–26 carbon atoms; ethoxylated, propoxylated, and mixtures ofethoxylated and propoxylated ethers of fatty alcohols with from about12–26 carbon atoms and a degree of ethoxylation and propoxylation ofbelow about 50; and mixtures thereof.

Even more preferred are branched-chain aliphatic fatty alcoholshaving from about 12–26 carbon atoms. Even more preferred are isocetylalcohol, octyldecanol, octyldodecanol and undecylpentadecanol; and mostpreferred is octyidodecanol. Such preferred aliphatic fatty alcohols areparticularly useful in combination with the volatile liquid siliconeoils discussed herein to adjust the average solubility of the solvent.

3. Non-Polar, Non-Volatile Oils

In addition to the liquids discussed above, the solvent for thecross-linked siloxane elastomer may optionally include non-volatile,non-polar oils. Typical non-volatile, non-polar emollients aredisclosed, for example, in Cosmetics, Science, and Technology, Vol. 1,27–104 edited by Balsam and Sagarin, 1972; U.S. Pat.

Depending on the compatibility of thecolorant, it may be included in either the aqueous phase or the oilphase.

With regard to the oil compatible colorants, there are no specificlimitations as to the pigment, colorant or filler powders that can beused in the composition. Each may be a body pigment, inorganic whitepigment, inorganic colored pigment, pearling agent, and the like.Specific examples are talc, mica, magnesium carbonate, calciumcarbonate, magnesium silicate, aluminum magnesium silicate, silica,titanium dioxide, zinc oxide, red iron oxide, yellow iron oxide, blackiron oxide, ultramarine, polyethylene powder, methacrylate powder,polystyrene powder, silk powder, crystalline cellulose, starch,titanated mica, iron oxide titanated mica, bismuth oxychloride, and thelike.

Also useful herein are pigment and/or dye encapsulates suchnanocolorants from BASF and multi-layer interference pigments such asSicopearls from BASF.

It is preferred that the oil compatible colorants, whether they bepigments/powders, be surface treated to provide added stability of colorand ease of formulation. Hydrophobically treated pigments are morepreferred, because they may be more easily dispersed in the solvent/oilphase. In addition, it may be useful to treat the pigments with amaterial that is compatible with a silicone phase. Particularly usefulhydrophobic pigment treatments for use in water-in-silicone emulsionsinclude polysiloxane treatments such as those disclosed in U.S. Pat. No.5,143,722. Also preferred are pigment/powders having a primary averageparticle size of from about 5 nm to about 100,000 nm, more preferablyfrom about 50 nm to about 5,000 nm, most preferably from about 100 nm toabout 1000 nm.

For instance, lakes are either a pigment that is extendedor reduced with a solid diluent or an organic pigment that is preparedby the precipitation of a water-soluble dye on an adsorptive surface,which usually is aluminum hydrate. There is uncertainty in someinstances as to whether the soluble dye precipitates on the surface ofthe aluminum hydrate to yield a dyed inorganic pigment or whether itmerely precipitates in the presence of the substrate. A lake also formsfrom precipitation of an insoluble salt from an acid or basic dye.Calcium and barium lakes are also used herein. Uncoated inorganiccolorants are also suitable aqueous compatible colorants.

No. 5,688,831 toEl-Nokaly et al.; and Examples of suitable moistures can be found inCosmetic Bench Reference, pp. 1.22, 1.24–1.26 (1996).

Emulsifiying crosslinked organopolysiloxane elastomers can also be used.As used herein “emulsifying” refers to a crosslinked organopolysiloxaneelastomer having at least one polyoxyalkylene unit.

A binder is also an essential component of the claimed composition. Thebinder acts to provide cohesiveness between the components (e.g., as anemulsion stabilizer) of the claimed composition that tends to improveskin adhesion of the invention (e.g., acts as a film former). Improvingthe long wear and non-transfer performance of the present compositionsis quite desirable.

Optional Ingredients

Shine Control Agents

Suitable ingredients that improve and/or regulate the condition of theshiny appearance of skin are referred to herein as “shine controlagents”. Shine control agents may be included in the compositions of thepresent invention.

A frequent, undesirable condition is “oily skin”, which results from theexcessive amount of sebum and sweat that is excreted onto the skin.Sebum is an oily mixture, composed principally of squalene,triglycerides, fatty acids and wax esters. Sebum is produced in thesebaceous glands of the skin. Oily skin is associated with a shiny,undesirable appearance and disagreeable tactile sensation. Sweat ispredominantly water with trace quantities of dissolved inorganic saltssuch as sodium chloride and potassium chloride.

Typically, shine control agents are porous in nature. These agents, whenapplied to the skin provide a reservoir to absorb excess moisture intothe pores, hence reducing the visible quantity of moisture on the skin.

Without being limited by theory, it is believed that it is preferable tocombine the use of effective porous, absorbent materials withnon-absorbing spherical materials. The latter emphasizes the effect ofdiffuse reflection over problematic specular reflection, causing anoptical modification to the skin and hence a reduction in the shinyappearance of the skin. The combination of absorber and non-absorbingspherical particles is preferable because it allows development of aproduct with optimum shine control as well as providing a product withthe best tactile sensory performance.

Suitable shine control agents include, but are not limited to, silicas,magnesium aluminum silicates, talc, sericite and various organiccopolymers. Particularly effective shine control agents includesilicates or carbonates that are formed by reaction of a carbonate orsilicate with the alkali (IA) metals, alkaline earth (IIA) metals, ortransition metals, and silicas (silicon dioxide). Preferred shinecontrol agents are selected from the group consisting of calciumsilicates, amorphous silicas, calcium carbonates, magnesium carbonates,zinc carbonates, and combinations thereof. Some specific examples of thesilicates and carbonates useful in this present invention are more fullyexplained in Van Nostrand Reinhold's Encyclopedia of Chemistry, 4^(th)Ed. pp155, 169, 556, and 849 (1984).

Synthetic versions of the shine control agents, particularly silicates,are preferred. Examples of synthetic silicates useful in the presentinvention are Hubersorb 250® or Hubersorb 600®, available from J MHuber.

Shine control agents that primarily comprise silicas are preferred overthose materials comprising mainly silicates and/or carbonates when usedfor moisture and shine control. Most preferred silicas are in the formof microspheres and/or ellipsoids, as they have been found to contributegood skin feel characteristics in addition to efficient moistureabsorption. Silica ellipsoids useful in the present invention areavailable from DuPont as ZELEC Sil and Kobo as Silica Shells. Silicamicrospheres are available from Kobo as MSS-500, MSS500/3, MSS-500H,MSS500/3N, MSS-500N and MSS 500/3N; Presperse as Spheron L1500, SpheronP1500. Fumed versions of silica can also be used with Aerosil fromDegussa and Cab-O-Sil from Cabot both being particularly useful.

Amongst the silicate series, magnesium aluminum silicates are useful, inparticular Sebumase, available from Miyoshi Kasei.

When silicas, particularly silica ellipsoids and silica microspheres areintended to be the main means for moisture absorption, it is preferredthat the absorbent powder comprise from about 1% to about 40%; morepreferably from about 1% to about 25%, and most preferably from about 2%to about 10%, by weight of the composition, of silicas.

Starch-based materials may also be used as shine control agents. Usefulexamples are Natrosorb W and Natrosorb HFW, DryFlo plus and DryFlo AFpure from National Starch and Chemical Company.

Also found to be useful are methacrylate-based polymeric materials. Theycan be used either in conjunction with a dimethicone copolymer or asmethacrylate-based copolymers. Specifically, useful examples are:Microsponge 5640 w. Glycerin, Polytrap 6603 available from Enhanced Dermtechnologies; DSPCS-12 series and SPCAT-12 from Kobo; Poly-Pore 200series from Amcol.

Optionally, yet preferably, the compositions of the present inventioncontain spherical particles having an average particle size diameter of10 or greater, preferably greater than 15, more preferably greater than20 microns. The particle diameter is understood to be that of elementaryor primary particles.

Preferred spherical particles include, but are not limited, to polymericparticles chosen from the methylsilsesquioxane resin microspheres suchas for example those sold by Toshiba silicone under the name Tospearl145A; microspheres of polymethylmethacrylates such as those sold bySeppic under the name Micropearl M 100; the spherical particles ofcrosslinked polydimethylsiloxanes, especially such as those sold by DowCorning Toray Silicone under the name Trefil E 506C or Trefil E 505C,sphericle particles of polyamide and more specifically Nylon 12,especially such as those sold by Atochem under the name Orgasol 2002DNat C05, polystyerene microspheres such as for example those sold byDyno Particles under the name Dynospheres, ethylene acrylate copolymersold by Kobo under the name FloBead EA209 and mixtures thereof. Alsofound to be useful is Ronasphere LDP from Kobo Inc

Optionally, the compositions of the present invention can furthercomprise a skin-conditioning agent. These agents may be selected fromhumectants, exfoliants or emollients.

Humectants are polyhydric alcohols intended for moisturizing, reducingscaling and stimulating removal of built-up scale from the skin. Typicalpolyhydric alcohols include polyalkylene glycols and more preferablyalkylene polyols and their derivatives. Illustrative are propyleneglycol, dipropylene glycol, polypropylene glycol, polyethylene glycol,sorbitol, hydroxypropyl sorbitol, hexylene glycol, 1,3-butylene glycol,1,2,6-hexanetriol, ethoxylated glycerin, propoxylated glycerin andmixtures thereof. Most preferably the humectant is glycerin

Exfoliants according to the present invention may be selected fromC2–C30 alpha-hydroxycarboxylic acids, beta-hydroxycarboxylic acids andsalts of these acids. Most preferred are glycolic, lactic and salicylicacids and their ammonium salts.

alpha-hydroxyoctacosanoic acid

When the conditioning agent is an emollient it may be selected fromhydrocarbons, fatty acids, fatty alcohols and esters. Isononylisononanoate is the most preferred hydrocarbon type of emollientconditioning agent. Other hydrocarbons that may be employed includemineral oil, polyolefins such as polydecene, and paraffins such asisohexadecane (e.g. Permethyl 99® and Permethyl 101®). Preferably, thecompositions of the present invention are substantially free ofsemi-solid hydrocarbons such as petrolatum, lanolin and lanolinderivatives, sterols (e.g., ethoxylated soya sterols), high molecularweight polybutenes and cocoa butter. By “substantially free,” as usedherein, means that the concentration of the semi-solid hydrocarbons arepreferably less than 10%, more preferably less than 5% most preferablyless than 2% and even more preferably 0%. Without being limited bytheory, such semi-solid hydrocarbons tend to mask the sensory benefitsof the siloxane elastomer compositions such as the non-greasy, lightfeel of the present invention.
